Nos. 1,232,104, 1,416,890 and 1,416,891. lgn the employment of this inveiition in the use and-practice of those inventions under conditions wherein the contents of the bowl are substantially in a state of li uid balance, the carrier liquid onvone side' oil a diaphragm within the bowl, such as the diaphragm 9, will substantially balance the substance to be separated and the carrier `li uid on the other side of such diaphragm willen the bowl 1` is rotating. The result will be that carrier liquid is vdelivered to its proper zone at the wall of the bowl prior to coming into contact with the substance to be Se limitedl and without such mixing with other substances lwithin the bowl as .might produce undesirable characteristics in the de-Waxed oil. The (le-waxed oil occupies the inner zone of the bowl and the carrier liquid does not pass through it in reaching its proper zone but it reaches its proper zone by bein directed upon the surface of the carrier iquid that occupies the space on one side of diaphragm 9 and holds in balance the contents of the bowl on the other side of the diiphragm.
